A solution of p-hydroxybenzoic acid (0.138g, 1 mmol) in 10 ml ethanol was added with stirring to a solution of dimethylamine (0.450g, 1 mmol) in 10 ml of distilled water at 303 K. After some time, a white precipitate was obtained. The white precipitate was dissolved in ethanol and colourless single crystals suitable for X-ray diffraction were obtained by slow evaporation of the ethanol solution.
All H atoms were located in a difference map, but positioned geometrically with O—H = 0.82Å, N—H = 0.90Å and C—H = 0.93–0.97 Å and allowed to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C,N) or 1.5Ueq(Cmethyl,O).
